In 2008, Steele competed in his first Olympic Games – Beijing 2008. He ran a personal best time of 44.94 seconds in reaching the semi-final in the individual 400 m event. As part of the Great Britain team, he finished fourth in the final of the 4x400m relay - 0.6 seconds away from a medal. However, in September 2016 it was confirmed that the Russian team, who had beaten Great Britain to bronze in this race, had been disqualified due to the retesting of Denis Alexeev's urine sample, which tested positive. Consequently, the British team was promoted to the bronze medal position.[2]
